Is simple belief in Jesus enough to be saved?

Commitment is said to be.  I used to know someone whose Christian friends described him as a "believer", meaning that he accepted the Christian world view of sin, salvation by grace and so on, but he had not personally repented and committed, meaning that by those standards he wasn't saved.  I'd actually contrast faith with belief in that sense.

You mean believing that He existed? Even most atheists are aware of that historical fact.

I believe he was a person at one point in time. Do I know him personally? Nope.

The Bible is clear and consistent about salvation.

You need to believe in Jesus Christ.

If you believe in Jesus then you believe in what he taught.

If you believe in what he taught then you will do what Jesus taught.

The Bible states that you need to be a hearer of the Word and a DOER of the Word.

If you truly Believe in Jesus, you will DO what Jesus taught and live a Christian life.

James 1:22 “But be ye doers of the word, and not hearers only, deceiving your own selves.”

The following scripture can answer your question: James 2:19. When John 3:16 says to exercise faith, what does that sound like it means?

No to find out what to do read the bible.  Matthew 25:40 in fact read that whole chapter and see the judgment given to the righteous and the one for the wicked.

Wow, so many people seriously think a deity made a magic torture dungeon.  How are y'all not embarrassed?!?

Yes. For example Satan believes in Jesus and Satan is saved.

Scriptures say that belief in Jesus will save you and then scriptures also say belief in Jesus will not save you. I could show you but it will take awhile for me to find them. John Chapter 5:39-40. When ya find the truth and do what He says then you shall know the truth and the truth shall set you free. Therefore only you by your choice of doing what the truth tells you to do has set you free. See the contradiction...lol Source, as some preachers say, my version of the bible.

Before that it is Daniel 10:12.  Then the process begins.
